COMPRESSIBLE TYPE-JUSTIFYING SPACE AND METHOD OF MAKING THE SAW. 3-

Application filed March 13, 1912. Serial No. 883,611.

To all whom it may concern:

Be it known that I, WILLIAM M. KELLY, a citizen of the United States,residing at New York city, county of Kings, and State of New York, haveinvented certain new and useful Improvements in CompressibleType-Justifying Spaces and Methods of Making the Same, fully describedand represented in the following specification and the accompanyingdrawings, forming a part of the same.

This invention relates to compressible spaces forusein hand or machine.I Theespecial objectof the invention is to provide a compressiblespacesuch that the adjacent type will be truly alined insetting, and thecompression of the spaces in justii'ying shall not produce a distortioninterfering with the proper position of the type.

Further objects of the invention are to mure'the'se results in a spacethat takes a I permanent set upon compression, so that the length of'line may notsubsequently change because of any resiliency of thecompressed spaces, to prevent molding material entering between thecompressible spaces and type," and to provide a construction which shall'be simple and cheap of manufacture.

In the-accompanying drawings forming a part of this specification, theinvention is illustrated-as embodied in its most complete and preferredform, and the construction illustrated will "now be described in detailand the features forming'theinvention then specifically pointed out intheclaims.

In the drawings: Figure 1 is-a perspective a view of a "rectangularnon-compressible spaizeforming the blank, from which my improvedcompressible space is formed in the preferred embodiment of theinvention. Fig. 2 is a perspective view showing the same space after ithas passed under the forming die to produce the improved compressiblespace, and Fig. 3 is'a vertical central section of the complete space inplace meets thetype. i

'- --Referring to Figs. 1 and 2, the bodyofthe' space'is shown at 10 andit will-be seen that the action of the forming die upon the body hasbeen to punch out two cylindrical bosses 11 and 12 upon one side of thespace, the spacing faces of the bosses being in the same plane andparallel with the side of'the Specification of Letters Patent.

" space, and to form on the other side of the bosses during the punchingoperation. Re-

ferring to F ig. 3, it will be noticed that the faces 11 and 12 on oneside of'the space and the surfaces 16, 17 and 18 on the other side formrespectively 'two parallel planes against which the type a may squarelyabut.

In justifying, when the line is being compressed to the desired length,the, metal from the bosses flows back into the tive cavities from whichit had he'eniirivn by the forming die and in this way the linealdimention of thespace is decreased while at the sametime the parallelismof the spacing surfaces remains undisturbed, and no distortion of'thetype occurs.

R It will be noted that the compression action is similar in manyrespects to the closing of a sectional telescope, this contrac- V vstance, an almost purely shearing "resistance is ofi'ered tocompression, the movemntunder compression, however, being substan tiallysimilar to that oftelesco'pio slides. The movement beingalmost wholly ifnot entirely'at right angles tothe vertical plane ofthe space, and thematerial of thespac'e being more "or less plastic in'its nature, thespace-ofi'ers a substantially uniform resistance to the com 'res'sionforce. v v

'By the'formmg die 'a lip 15, 15 also is preferably formed 'a't'eachendof the space upon "the same, side as the 11 and 12',

and preferably tapersinto a relatively thin andcurved extremityasbest'shown in Fi 3. This lip forms a sealing headto facili tate themaking of electrotypes from the set up matter. The 'spaoe b etwi'a'enthevbody'lfi) molding material entrapment the easy r'e movalof'the them.his is prevented by the lip 15 which extends, as shown, into con-"tactwith the typewthereby forming a seal *ing'head which preventsfurther downward flow of the plastic material; the upper surface'of thespace, as indicated at 21, formand the type a weuiaordinarily s11 site 1ing a comparatively smooth even bed from which the mold is readilyremovable. The taper given to the lip allows it to be compressed withoutundue distortion during the justifying operation and to maintainthe sealintact regardless of the extent of compression of the space.

While in the case chosen to illustrate the invention, a pair ofcylindrical bosses with related cylindrical cavities are shown asdisclosing one of its important features, it is obvious that thecomparative size, or location, or form, or number of the spacingprojections provided may be widely varied n practice without departingfrom the spir t of the invention, and this is also true of" theparticular form that may be given to the sealing lip described. I donot, therefore, limit myself to the particular form and arrange'ment ofany of the parts as herein shown and described. It will be understood,also, that while the spacing projections are preferably formed bypunching them from the body of the material, and this method forms aspecific feature of the invention, they may be cast or otherwise formed,within the invention considered more broadly. The spaces may be madeofany material suitable to secure the action desired. 1 have used leadwith fair success, but prefer a slightly harder material and havesecured the best results with a mixture of lead antimony and tin inabout the proportions of eighty-eight parts lead, four parts antimonyand eight parts tin. This is substantially the same as some typematerial and has the advantage in use that the spaces may be thrown intothe melting pot with the type for remelting.

, What is claimed is:

1. A ncompressible space having a substantially rectangular body, and aplurality of cylindrical spacing projections located on one side-10f andcompressible into the body, without any bending movement duringcompression and formed to oifer a uniform resistance to the compressionforce.

'2. A compressible space having a substantially rectangular body, aplurality of cylindrical projections located on one side of the body,and a plurality of related cylindrical cavities on the opposite side ofthe body, the said projections being adapted to enter the said cavitieswhen the space is compressed, w thout any bending movement of the proections.

3. A compressible space compressing a sub-= stantially rectangular bodyand a plurality.

.of lateral spacing projections carried by'the body, the outer surfaceof said projections,

being in a plane parallel with the opposite side of the body, and theprojections being uniformly compressible into spaces within the body.

4. A compressible space having an inelastic and compressible sealinghead whereby molding material is prevented from fiowtions punchedtherefrom without open rupture between the projections and body.

' T -The method of producing compressible spaces, which consists inforcing portions of the body of the space outward to form spacingprojections and cavities in the body into which the metal of theprojections returns on compression, the changes in form taking placewithout open rupture between the projections and body.

8. The method of producing compressible spaces, which consists inforcing portions of the body of the space outward to form cylindricalspacing projections andcavities inthe body into which the metal of theprojections returns on compression, the changes in form taking placewithout open rupture between the projections and body.

9. In combination, the body 10,-. projections 11 and and cavities l3 and14, the projections being punched from the cavities without open rupturebetween the.pro-- jections and body.

10. In combination, the body 10, projections 11 and 12, cavities 13 and14, and the lip 15, the projections being punched from the cavitieswithout open rupture between the projections and body.

11. A compressible space comprisinga body having a plurality of spacingprojec tions compressible into the body by a tele sco ic action. a a

testimony whereof, I have hereunto set my hand, in the presence of twosubscribingwitnesses.
